Cons

The K320 is an entry-level wireless keyboard from Logitech. The keyboard works with a 2.4GHz USB wireless receiver which can be used with multiple wireless devices at once. The K320 offers a basic, full-size layout, lacking the customization functions of more advanced models, as well as comfort add-ons like the K350's palm rest. Two AA batteries last in the device for about three years, and a three-year warranty is standard. The K340, another more expensive model, offers a more compact design along with quieter typing and programmable F-keys.
